Comment Unfortunately named JPEG-XL (Score 1) 17
I read the reasoning (below) for the name on the Wikipedia page, but it still seems unfortunate for something that's suppose to be smaller than regular JPEG.
The name refers to the design committee (JPEG), the X designates the series of its image coding standards published since 2000 (JPEG XT/XR/XS), and L stands for "long-term", highlighting the intent to create a future-proof, long-lived format to succeed JPEG/JFIF.
It's like trying to figure out if the LHC is simply very big (Large Hadron-Collider) or just for smashing big particles (Large-Hadron Collider) - or both.
